WORKING PRINCIPLE
A
NEW EXCALIBUR
The NEW J11
EXCALIBUR unit is defined “electric piston pump”.
An electric piston pump is used for high pressure painting without
air (from this process derives the term ”airless”).
The pump is controlled by an electric motor coupled with a
reduction gear.
A cam shaft and a connecting rod allow to obtain the reciprocating
motion necessary to the working of the “pumping group” piston.
The piston movement produces a “vacuum”.
The product is sucked, pushed towards the pump outlet and
then sent to the gun through the flexible hose.
A electronical device on the side of the reduction gear casing,
allows to adjust and control the pressure of the material coming
out of the pump.
When the pump reaches the set value, the motor stops and
starts again when the value decreases.
A safety valve avoiding overpressure, guarantees the total
reliability of the equipment.
“Top Finish” version.
“Top Finish” version allows to choose between Airless and
Mistless painting.
The machine works with basic system Mistless and to choose
the airless system it is necessary to close the air supply and
replace the type of spraying gun.

• An irregular and marked spray on the sides indicates a low
working pressure. On the contrary, a too high pressure
causes a high fog (“overspray”) and waste of product.
• In order to avoid overthickness of paint, let the gun advance
sideways (right-left) when spraying.
• Always paint with regular parallel bands coats.
• Keep a safety and constant distance between the gun
and the support to be painted and also keep yourselves
perpendicular to it.
NEVER point the spray gun at yourselves or at
other people.
The contact with the casting can cause serious
injuries.
In case of injuries caused by the gun casting, seek
immediate medical advice specifying the type of
the product injected.
Recirculating-safety valve: when working at the
maximum pressure available, releasing the gun
trigger sudden increases of pressure can occur.
In this case, the recirculating-safety valve opens
automatically eliminating part of the product from
the recirculating tube.
